<a name="index-guile-architectures"></a>
<a name="index-_003cgdb_003aarch_003e"></a>

<p><small>GDB</small> uses architecture specific parameters and artifacts in a
number of its various computations.  An architecture is represented
by an instance of the <code>&lt;gdb:arch&gt;</code> class.
</p>
<p>The following architecture-related procedures are provided by the
<code>(gdb)</code> module:
</p>
<dl>
<dt><a name="index-arch_003f"></a>Scheme Procedure: <strong>arch?</strong> <em>object</em></dt>
<dd><p>Return <code>#t</code> if <var>object</var> is an object of type <code>&lt;gdb:arch&gt;</code>.
Otherwise return <code>#f</code>.
</p></dd></dl>

<dl>
<dt><a name="index-current_002darch"></a>Scheme Procedure: <strong>current-arch</strong></dt>
<dd><p>Return the current architecture as a <code>&lt;gdb:arch&gt;</code> object.
</p></dd></dl>

<dl>
<dt><a name="index-arch_002dname"></a>Scheme Procedure: <strong>arch-name</strong> <em>arch</em></dt>
<dd><p>Return the name (string value) of <code>&lt;gdb:arch&gt;</code> <var>arch</var>.
</p></dd></dl>

<dl>
<dt><a name="index-arch_002dcharset"></a>Scheme Procedure: <strong>arch-charset</strong> <em>arch</em></dt>
<dd><p>Return name of target character set of <code>&lt;gdb:arch&gt;</code> <var>arch</var>.
</p></dd></dl>

<dl>
<dt><a name="index-arch_002dwide_002dcharset"></a>Scheme Procedure: <strong>arch-wide-charset</strong></dt>
<dd><p>Return name of target wide character set of <code>&lt;gdb:arch&gt;</code> <var>arch</var>.
</p></dd></dl>

<p>Each architecture provides a set of predefined types, obtained by
the following functions.
</p>
